Patent number: 7691338Abstract: A catalytic combustor (14) includes a first catalytic stage (30), a second catalytic stage (40), and an oxidation completion stage (49). The first catalytic stage receives an oxidizer (e.g., 20) and a fuel (26) and discharges a partially oxidized fuel/oxidizer mixture (36). The second catalytic stage receives the partially oxidized fuel/oxidizer mixture and further oxidizes the mixture. The second catalytic stage may include a passageway (47) for conducting a bypass portion (46) of the mixture past a catalyst (e.g., 41) disposed therein. The second catalytic stage may have an outlet temperature elevated sufficiently to complete oxidation of the mixture without using a separate ignition source. The oxidation completion stage is disposed downstream of the second catalytic stage and may recombine the bypass portion with a catalyst exposed portion (48) of the mixture and complete oxidation of the mixture.Type: GrantFiled: March 10, 2004Date of Patent: April 6, 2010Assignee: Siemens Energy, Inc.Inventors: Mary Anne Alvin, Dennis Bachovchin, Eugene E. Smeltzer, Thomas E. Lippert, Gerald J. Bruck

Patent number: 6701764Abstract: A method of making a tube having an expanded region which includes the steps of providing an elongated metal tube, preparing the tube to be expanded, and, exerting a generally uniform outwardly radial force to create the expanded region. During the preparation step, a region of the tube is annealed by applying heat. The outward radial force may be created by pressurizing the tube, by freezing water within the tube or by axially rotating the tube.Type: GrantFiled: September 27, 2001Date of Patent: March 9, 2004Assignee: Siemens Westinghouse Power CorporationInventors: Gerald J. Bruck, Eugene E. Smeltzer, Francis A. Kramer

Patent number: 6511076Abstract: A gasket (1) is made by repetitively spirally winding a fiber (3) back on itself in a closed path. The gasket (1) so made has a multi-layer spiral winding (1) formed in a loop (5). The fiber (3) can be wound at a constant wrap rate to form a gasket with a uniform cross-section around the loop. Alternatively, the wrap rate can be varied, increased to increase cross-sectional bulk, and decreased to reduce cross-section bulk around the loop (5). Also, the spiral winding (7) can be applied over a core (13) of either strands of the fiber (3) or a dissimilar material providing a desired property such as resiliency, stiffness or others. For high temperature applications, a ceramic fiber (3) can be used. The gasket (1) can have any of various geometric configurations with or without a core (13).Type: GrantFiled: September 21, 2000Date of Patent: January 28, 2003Assignee: Siemens Westinghouse Power CorporationInventors: Gerald Joseph Bruck, Mary Anne Alvin, Eugene E.

Patent number: 5944859Abstract: A filter element for separating fine dirty particles from a hot gas. The filter element comprises a first porous wall and a second porous wall. Each porous wall has an outer surface and an inner surface. The first and second porous walls being coupled together thereby forming a substantially closed figure and open at one end.
